What are the differences between return codes and exceptions in C++?

Return codes are values returned by functions to indicate success or failure, while exceptions are objects that signal errors.

When should I use return codes instead of exceptions?

Use return codes for simple error handling in performance-critical code, and exceptions for complex error management.

Can you give an example of using exceptions in C++?

Sure! You can use a try-catch block to handle exceptions. For example:

try {
    // code that may throw an exception
} catch (const std::exception& e) {
    // handle the exception
}

Are there any performance implications of using exceptions?

Yes, exceptions can introduce overhead, especially if they are thrown frequently. It's important to balance readability and performance.
